Hydrocolloid patches sit over a blemish, absorb fluid overnight and flatten it faster than leaving it alone — and crucially, they stop you touching it, which is what turns a spot into a scar. Ultra-thin versions are discreet enough to wear under makeup or during the day.

Apply to clean, dry skin before any serum or moisturiser, or the patch won't adhere. Shop Korean acne patches from COSRX, Anua, Pyunkang Yul, VT Cosmetics, TIAM, Isntree and more.
